No such thing. Ask away!

!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must be legitimate questions. All post titles must include a question.

All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.



Rule 2- Your question subject cannot be illegal or NSFW material.

Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.



Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here.

I took a ton of pictures at an event. Unfortunately the autofocus of my cam is a bit wonky and this lead to blurry pictures. Does anyone have an app or way to restore details on the unfocused object? I also have the raw files of these pictures if that helps.

You can't 'restore' those details because the camera didn't capture them. The light was not focused on the same plane as the sensor

The best you can do is use an AI sharpening tool which will essentially guess what a sharp image would look like

https://duckduckgo.com/?q=ai+image+sharpening

From one of those sites: "The Focus model reduces lens blur caused by missed focus. This is the toughest use case and won’t recover 100% of your photos. When it works, though, it works really well and can completely recover a throwaway image."

You don't have a lot of options outside of an an unsharp mask or your standard sharpening tools. There are ai tools that are starting to come out that will basically rebuild your photo, but your YMMV and they require a certain level of technical know how.

[–] [email protected] 1 points 1 year ago (1 children)

Do you have any recommendations regarding the AI tools? Technical experience should be sufficient to run and configure tools when provided. Would be nice if there was a tool to sharpen a face based on other source pictures provided.

[–] [email protected] 2 points 1 year ago (1 children)

Take a look at ChaiNNer and it's model wiki. Just a tip, you may need to downscale your image and then upscale it to get the sharpening to kick in. A lot of these models are based off of 512x512 sample images.

If you want to spend money, Topaz Labs might have something to offer, but I primarily deal worth video so im not super familiar with their still image offerings.

Will have a look at ChaiNNer in case topaz sharpen ai doesn't get the results I want.

[–] [email protected] 3 points 1 year ago (1 children)

Topaz Labs Sharpen AI is paid software, but does have the ability to specifically address out of focus photos. It's hit or miss but can make a difference. I think you can try it for free, it's worth a shot.

[–] [email protected] 1 points 1 year ago (1 children)

I'll try that one out. If it works well enough I'm willing to pay.

[–] [email protected] 2 points 1 year ago (1 children)

Let me know if you need the torrent. It's a great one.

[–] [email protected] 3 points 1 year ago (1 children)

Thx, but it seems to be a one time payment. If it where a subscription based model the torrent would be needed.

Your success will be highly dependant on how out of focus the images are. Slightly out of focus? You'll probably be able to get it looking mostly right minus some small details. But very out of focus? The computer will never know what was there, because the camera never actually captured what it was.

[–] [email protected] 1 points 1 year ago (1 children)

You will not be able to get the actual detail back unfortunately... However there are some of the ai tools that give best guesses as to what should have been there and like a sort of auto-generated picture can look extremely plausible. I have seen outputs from them and think the latest Google pixel phone will have it built in, but not sure were to access it online

Yeah I played around with different tools yesterday. Topaz sharpen AI was pretty much useless for what I need. But ChaiNNer with different models is looking promising so far to save at least some of the pictures I have.
